Localised herpes zoster infections spread by direct contact with active skin lesion, but airborne transmission is rare. We report a case of varicella from airborne transmission of a localised herpes zoster infection in a family. The patient was a 15-year-old boy who had never been vaccinated against the varicella-zoster virus (VZV). He likely developed varicella from his father, whom the patient lived with. The patient’s father developed a localised herpes zoster infection 2 weeks prior. The patient’s varicella was hypothesised to be due to VZV spread via airborne transmission from the father’s localised infection. To decrease the number of varicella cases, routine vaccination of children against VZV is essential, and immunisation against VZV in middle-aged and elderly patients is also necessary.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
